This invention relates to. textile spindles and has'for its primary object to provide an improved spinning spindle which 1s provided with a self-contained lubricant receiv-' 5 ing reservoir which may be bodily removed with the spindle and its support from the bolster. r

It is another and more particular object of the invention'toprovide means particularly desi ed for use-in connection with silk spinning sp ster mounted inthesupporting railfor ieldable oscillating movement, said bolster aving a tapering socket or bore, a'spindle support consisting of a tubular body section and a section fitted within one end of said tubular section and havin a shank for frictional engagement in the holster socket, said latter section of the support being fornliied et into which the lower end of the spin e extends. i

It is a further general object of my invention to provide a consists of relatively few parts all very simply formed and which are capable of bein easily and quickly as sembled or disassem led.

With the above and other objects in view, the invention consists in the improved construction, combination and arrangement of the several elements as will be hereinafter more fully described, illustrated in the accompanyin draw' and subsequently incorporated m the su joined claims;

- .Inthe drawing wherein I have illustrated one practical embodiment of my invention and in which similar reference characters Pdesignate corresponding parts throughout the several views:

Fig. 1 is avertical sectional view of a textile spindle constructed in accordance with one embodiment of the invention; and M Fig. 2 is asection taken on the line 2-2 ofFigl.

Re erring in detail to the drawin ,5 designates the rail of a spinning mac ine having an opening therein to receive the shank of a bolster 6. This bolster at its upper end is formed with a head or flange 7 engaging. the upper surface of the rail. A washer of felt, leather or other suitable material indicated at 8 surrounds the shank of the bolster and is held, against the under side of the rail by a coilr spring 9. The

indles, and including a, bolinmng spindle as above lower .1. intima e, shank is t breaded to receiv 'aifnut lowhereby'the tension of the spring '9 may be regulated as desired-ix The head 7 at the bolster is. formed uponits per meter with an upwardly and l'atera1- 00' ly pro]ect1n arm 11 in the upper end of which a sli ing pm 12 is mounted. The

bolster 6 is further formed with an axially extending tapered socket or bore 13. w

The spindle support as herein shown 'consists of a tubular body section 14 open at. its opposite ends. The ends of this tubular support 14 are counterbored to provide the annular shoulders 15 and 16 respectively. The outer race rings 17 and 18 of the upper and lower ball bearings engage against the shoulders 15 and 16 and have a ,tight mechanical fit within the counterbored ends of the support 14. In the lower end of this support the base section 19 has a driven fit. This base section is formed with a shank 20 which is adapted to be tightly fitted and frictionally held within the socket 13 of the bolster. This shank is preferably. tapered and-so formed as to be freely removable from the socket 13. The upper end of the base section 19 of the supportalso engages the outer race ring 18 and thus securely holds this ring upon the shoulder 16 and agiiinstlongitudinal shifting movement. T e base section 19 is formal with a cavity or chamber 20 to receives. suitable lubricant, in which the lower end of the spindle is submer' (1.

T e spindle 21 is formed with a diametrically reduced portion '22 to; thereby provide the shoulder 23 against which the inner race ring'24of the upper ball bearing is engaged, said race ring ha a tight fit around the reduced portion of t e spindle.-

25 designates the. ball bearings interposed between the meanings 17 and 24 and engaged in suitable races formed thereon. The lower end portion of the spindle is again reduced in diameter as seen at 26, said end portion ofthe spindle extending into the lubricant contained in the'ca-vity 20. A second shoulder 27 is thereby formed upon the s indle with which the inner race ring 28 o the lower ball bearing is ened. 29 designates the bearingballs which are interposed between this ring and the outer race ring 18. These upper andlower ball bearings which su port the spindle for free rotation within t e tubular 110 the periphery thereof immediately adjacent the upper ball bearing.

- the periph'e sleeve 14. "By t 32 designates the whirl with which the driving band or belt is adapted to be engaged. This whirl, which is in the form of a sleeve, surrounds the tubular supporting member 14. At its upper end the wall of the whirl is relatively thick and formed with an internal annular flange 33 which projects downwardly into the upper end of the supporting member 14. This end of the whirl s securely fixed upon the body of the spindle 21. At its lower end the whirl s eeve is provided with an outwardly projecting annular flange 34, and the inner end of the pin 12 mounted in the arm 11 overlies this flan and acts as a stop to prevent vertical fting movement of the spindle and its support with respect to the Y bolster.

The wall of the supporting member 14 immediately above the lower bearing is rovided with an openin 35 throng w ich the lubricant may be ed intothe chamber 20. The whirl sleeve is also provided with a lurality-of openings, 36'adapted to coinci e with the o ning 35 and affording a means to supp y oil to the chamber or cavity 20. v i

From the foregoing description considered in connection with the accompanyin drawing, the construction of my improve spindle will be fully understood. In .the rotation of the sleeve whirl and spindle at high speeds, the centrifugal force induces a suction through the bore or duct in the spindle whereby the lubricant oil is drawn upwardl from the chamber 20 and thrown outwar y'throu h the upper end of the said duct u on the parts 0 the upper ball bearing; e oil will fall through the passage between the wall of the sleeve 14 and of the spindle and thereby thoroug y lubricate the parts of the lower ball bearing and finally return to the cavit 20. Thus, in the rotation of the spin e the level of the oil will be lowered so that it will not be thrown upwardly by agitation above the lower'ball bearing and not escape throu h the opening in the e provision of this oil chamber or reservoir contained within the spindle and whirl su port, it will be observed that the in lo together with said support may be as a unit and removed re or duct 30 extending through .bodiments and I therefore from the bolster 6. Thus spindles of difierent sizes may be interchanged, or broken spindles quickly removed for any necessary attention. The several parts of the device the preferred form, construction and relative arrangement of the various elements, it

is manifest that the invention may also ber exemplified in numerous alternative emreserve the privilege of adopting all such legitimate changes as-may be fairly embodied in the spirit and scope of the invention ascl'aimed.
